5. One strategy in a snowball fight is to throw a snowball at a high angle over level ground. While your opponent is watching the first snowball, you throw a second one at a low angle timed to arrive at your opponent at the same time as the first one. Assume both snowballs are thrown with a speed of 25 m/s. The first one is thrown at an angle of 70° with respect to the horizontal. (a) At what angle should the second snowball be thrown in order to arrive at the same point as the first? (b) How many seconds later should the second snowball is thrown after the first to arrive at your target at the same time?
